Title: Display control microcomputer with background color modifying circuit
Inventor: KAWAUCHI KOICHI
IPC: G06T11/00
Filed: 1991-12-09
Abstract: PURPOSE:To modify or emphasize the background color of a character display so as to display a clear character by providing an exclusive circuit to modify the background color of a character display and a terminal which sends the modified signals to the external to change video signals. CONSTITUTION:A character modifying circuit 20 for modifying the background color in a control microcomputer 1 for display and a mixer 21 externally located are provided. Assume that the output of the circuit 20 is specified, for example, to a green color and the display color of the corresponding part of a CRT 14 screen is blue in the lower half. On the other hand, assume the character display is '1'. At that time, OUT data without the background, which is the output of an OR circuit 9, outputs a prescribed signal and provides a background color display screen after deleting OUT. Moreover, the microcomputer 1 provides red color display character data, thus, the last display screen of the CRT 14 becomes a prescribed color display. Thus, the character display becomes conspicuous.

Abstract: PURPOSE: To prevent the flowing of a cutter by pushing wide equally in left and right sides so as to perform linear push cutting by setting the angles of both side cutting blades of a push cutter blade to be V shapes having uniform inclinations. CONSTITUTION: A push cutter blade A is reciprocated along a rail 6 together with a holder 5 by reversible inverse rotation of a male screw 7, and an article 10 to be cut on a table 9 is cut by the cutter blade A.

Filed: 1988-12-23
Abstract: PURPOSE:To easily broaden a dynamic range in simple constitution by providing a second gain switching means, which switches the output gain of a window function generating circuit so as to be inversely proportional to a gain switching quantity by means of a first gain switching means. CONSTITUTION:The input gain at the time of a small signal becomes larger by first gain switching mans 21 to 2N, and a delta/sigma modulating circuit 9 is made apparently equivalent to the handling of the input signal whose dynamic range is narrowed, and it is hardly affected by the narrowness of the dynamic range held by the delta/sigma modulating circuit 9. The apparent level change of the input signal is compensated by being switched so that the output gain of a window function generating circuit 10 becomes smaller by a second gain switching means 25 at the time of decimation, and the linearity of an A/D conversion can be held as the whole circuit. Thus, the dynamic range can be broadened in the simple circuit constitution.

Abstract: PURPOSE:To obtain orthogonal linearly polarized light having stable characteristics at a low cost by using reflection optical systems, such as multireflection optical prisms, for rotation of the plane of polarization and conversion of optical paths. CONSTITUTION:The laser beam of the linearly polarized light from a light source, such as semiconductor laser, is demultiplexed to two beams by a translucent mirror 1 inclined at 45 deg. with the optical axis or non-polarization beam splitter while the plane of polarization is maintained.
